:description: Migration guide for installing ESPHome on ESPs running Tasmota.

|
|
|
|
Migrating from previous Tasmota setups is very easy. You just need to have
|
|
ESPHome create a binary for you and then upload that in the Tasmota web interface.
|
|
|
|
Incompatible versions
|
|
---------------------
|
|
WARNING! Migrating via OTA on ESP32, from Tasmota v12 (with boot partition) and up is currently not possible! Trying it could soft-brick your device!
|
|
|
|
|
|
Getting the Binary
|
|
------------------
|
|
|
|
First create a configuration for your device. Then, generate and download the firmware image:
|
|
|
|
Using the Home Assistant add-on/dashboard
|
|
`````````````````````````````````````````
|
|
|
|
From the card of your device: open **the three dots menu** and select **Install** option.
|
|
|
|
.. figure:: images/dashboard-install.png
|
|
|
|
A new dialog will open. Click on **Manual download** option.
|
|
|
|
.. figure:: images/dashboard-install-manual.png
|
|
|
|
Finally, choose **modern format** in the last dialog.
|
|
|
|
.. figure:: images/dashboard-install-manual-modern.png
|
|
|
|
The build process of the firmware will start and the image will be automatically downloaded after its completion.
|
|
|
|
Using the command line
|
|
``````````````````````
|
|
|
|
From your configuration files folder, run
|
|
|
|
::
|
|
|
|
esphome <MY_DEVICE>.yaml compile
|
|
|
|
replacing ``<MY_DEVICE>.yaml`` with your configuration file and navigate to the ``<MY_DEVICE>/.pioenvs/<MY_DEVICE>/`` folder.
|
|
|
|
There you will find a ``firmware.bin`` file. This is the binary that you will upload.
|
|
|
|
Uploading the Binary
|
|
--------------------
|
|
|
|
To upload the binary, navigate to the Tasmota web interface and enter the
|
|
"Firmware Upgrade" section.
|
|
|
|
.. figure:: images/tasmota_main.png
|
|
:align: center
|
|
:width: 60.0%
|
|
|
|
In the "Upgrade by file upload" section, choose the binary you previously downloaded
|
|
|
|
.. figure:: images/tasmota_ota.png
|
|
:align: center
|
|
:width: 60.0%
|
|
|
|
If everything succeeds, you will see an "Upload Successful" message and ESPHome
|
|
will connect to the WiFi network configured in your .yaml file. 🎉

Happy Hacking!

|
.. note::
|
|
|
|
When using the :doc:`esp8266_pwm output </components/output/esp8266_pwm>` platform and
|
|
switching from Tasmota, you need to power-cycle the device once. After that
|
|
the dimming functionality will work as usual and no more power cycles are required.
|
|
|
|
About image size and ESP8266
|
|
----------------------------
|
|
|
|
ESP8266 has very limited storage space. Trying to upload a large image will cause the
|
|
upgrade process to fail.
|
|
|
|
Tasmota 8.2 introduced upgrading using gzipped binaries which are smaller in size and
|
|
make the upgrade process easier.
|
|
|
|
- If you are using Tasmota 8.2 or later (recommended) you probably will want to compress the firmware generated from ESPHome with ``gzip`` before uploading it.
|
|
|
|
- If you are using any version older than 8.2: first upload ``tasmota-minimal.bin`` from Tasmota repository. Then upload the firmware generated from ESPHome.
|
|
- Alternatively, first upgrade Tasmota to the latest version. Then use the first (gzip, recommended) method.
|
|
|
|
If you are using Tasmota 7.2+ it may be necessary to run the command ``SetOption78 1`` in the
|
|
Tasmota console and restart your device to be able to upgrade to esphome.
|
|
|
|
|
|
Automated migration from console
|
|
--------------------------------
|
|
|
|
You may also use Tasmota console to invoke the upgrade with just two commands:
|
|
|
|
::
|
|
|
|
OtaUrl http://<MY-ESPHOME:6052>/download.bin?configuration=<MY_DEVICE>.yaml&type=firmware-factory.bin&compressed=1
|
|
Upgrade 1
|
|
|
|
replacing ``http://<MY-ESPHOME:6052>/`` with the host and port of your ESPHome installation and ``<MY_DEVICE>.yaml``
|
|
with your device configuration file name.
|
|
|
|
If you need to use the uncompressed image for any reason, just remove ``&compressed=1`` from the above url.
